This is my concern, as well. We have some people at my place of work saying, “Working from home has been great! I’ve never been more effective and happy at my job.”, and then we have a smaller but more vocal group that says, “I hate working from home and it’s incredibly stressful. I want to go back ASAP.” I worry that the second group will “win” and the pendulum will swing the other way because of the latter group’s experience.
What we should really be aiming for is flexibility. Some people can be in the office, some can stay remote.
Personally, I dislike being in an office every day, but even more than that I hate the commute. If my manager forces me back, I’ll probably quit and look for a job/company that plans to allow remote work permanently. I’m trying to remain hopeful, however.
